The easiest seems to use build transformations [1] and/or write your own
variant. The package emacs-next provides 28 at exact version/commit
$(guix show emacs-next | recsel -P version) and using a Git checkout, so
you can try:
guix build emacs-next --with-commit=emacs-next=<commit>
where <commit> is the commit you are interested in. If it does not work
out-of-the-box, look “guix edit emacs-next” and then use it to adapt for
your use case.
Note that all the Emacs packages are “bytecompiled” with the Emacs 27 VM
provided by the package emacs-minimal (see guix/build-system/emacs.scm),
modulo some corner cases replacing the VM; for instance ’emacs-magit’
with ’emacs-no-x’.
Therefore, there is no guarantee that:
guix install emacs-next emacs-foo emacs-bar
works. It is high probable that it works because the Emacs bytecode
does not often change and generally they try hard to keep compatibility.
But who knows. :-)
It is not as easy to re-bytecompiled all the Emacs packages with another
VM because of these very corner cases. Two work-in-progress attempts:
- package parameters [2],
- package-with-explicit-emacs, the story starts here [3], or scroll [4].

Hope that helps,
